ALARM-SiGN AL FOR RAILROAD-CROSSINGS.

SPECIFICATION forming part of Letters Patent No. 294,207, dated February26, 1884:.

Application filed April 7,1883. (No model.) I

To aZZ whom it may concern-.-

Be it known that we, JOHN B. DEEDS and Josnrrr H. BLAKE, of TerreI-Iaute, in the county of Vigo and State of Indiana, have in Ourinvention relates to improvements in I that class of invention known asalarm-signals for railroad-crossings, and it has for its I object toprovide certain means whereby the train, on nearing the crossings, willoperate certain mechanism to produce an alarm, thus giving notice topersons of the approach of the train, and also frighten away live stockshould any be in the vicinity of the crossing. To these ends we placeabout one-fourth of a mile (more or less) on both sides of the cross- 25 ing a suitable lever or rocker bar fulcrumed in a standard forming abearing therefor, and we fasten to the straight or depending arm thereofthe endcof a wire of suitable strength, which extends alongside the railto the crossing, where its other end is fastened to an arm of a rockingrod which turns in suitable bearings, to which arm is also secured aspring. The other end of said rod is adapted, when the rocker-bar isactuated, to cause a vertitically-pivoted rod to oscillate against asonorous body, thus producing the alarm. The wire is designed to runthrough apipe or tubing, and around the rocker-bar and spring isarranged suitable boxing for housing of the parts as a protection fromthe weather.

In the accompanying drawings, A represents the railroad-track, and at asuitable distance 011 each side of the crossing, adjacent to the side ofthe track, is fulcrumed a lever or r rocker bar, B, in bearings l, thearm I) of which is curved and projects above the top of the track. Theother arm, I), is bent down ward, and is formed with an eye at the endfor the purpose of fastening thereto a wire, 0, which wire runs withinsuitable pipe or tubing, d, to protect it from frost, to the crossing,

where it is connected to an upright arm, 6, of a rod or rocker, C, saidrod being in a position at right angles to the track, and bent into armsat each end in such manner that said arms are maintained in an uprightposition, and turning and supported in bearings 2 and 3, which bearingsare arranged to support each end of the rod. Also, to the arm 6 isattached one end of a spring, K, of sufficient strength, the other endof which is secured to a pin, 4-; or, as is evident, it may be securedby any suitable equivalent means.

D is a post of sufficient height, the bearings 3 for the rod or rocker 0being arranged there on on a horizontal line with bearings 2 for saidrod. To the outside of post D is vertically pivoted a rod, E, which hasa bent and slotted end, 6. up through which extends the upright arm 0 ofthe rod or rocker O. This vertical rod E is adapted to oscillate fromthe motion imparted to it caused by the spring and by the depression ofthe rocker-bar by the wheels of a train coming from either direction,(for, while a description is given of the mechanism on one side of thecrossing, it will be understood that it is similarly provided on theother side,) and this rod being provided 011 its upper end with a hammeror clapper,

y, it strikes a bell, gong, or other sonorons body, G, 011 each side ofthe upper end of the post, to produce sound .for the purpose intended.

h h are indicators or hands attached to rod E, which move up and downwith the oscilla- 8 5 tion of the rod and tend to attract personsattention to their danger.

f is a pin or stop to arrest the rocker-bar and prevent its curved armfrom being thrown backward too far when drawn up by the re- 0 siliencyof the spring.

At F F are shown in dotted lines suitable boxes to inclose the workingparts, as a protection from the weather, which boxes it is intendedshall have holes in the sides and top 5 where it is necessary for anypart of the mechanism to project therethrough.

H is a platform on which is erected the post, as are also other of theparts; but it is obvious that it could be dispensed with or other simi-10o lar contrivance substituted.

It will be observed that the sounding body is located to some distancebeyond the side of the track, and the rod 0 is of length sufficient toconnect the operating mechanism with the oscillating rod E for producingthe alarm.

The operation is as follows: Each of the wheels of the cars passing overthe rocker-bar depresses it and throws its depending arm I) backward,which draws the wire, and'the wire thus drawn causes the rod or rocker Oto turn in its bearings, and the motion is thence iinparted to the rodE, which oscillates the alternate depression of the curved arm of therocker-bar by the wheels, and its restoration to position by the springcauses the oscillation of the rod between the bells, thus producing thealarm.

Having thus described our invention, what we claim is" 1. In arailway-alarm signal, the rocker-bar fulcrumed in the bearings-1, thewire '0, inclosed within tubing, both as described, in combination withthe spring, and rod G, turning in bearings, one end of which rodext-ends up through the slotted portion of rod E, and said rod E adaptedto be oscillated by the alternate depression of the curved rocker-bar'bent and slotted, the rod 0, turning in bearings and its outer endentering the slot in rod E, spring is, wire 0, and the rocker-bar, thewhole connected and designed to be operated substantially as set forth.

In testimony that we claim the foregoing as our ownwe affix oursignatures in presence of 40 two witnesses.

JOHN B. DEEDS.

JOSEPH H. BLAKE.
